1975 Western Pacific typhoon season
Typhoon June 1975
Typhoon June reached extraordinary intensity west of Guam in November 1975. Reconnaissance measured a central pressure of 875 hPa during a rapid deepening episode, while its offshore path limited the destruction on nearby islands.

STORM HISTORY
Explosive intensification west of Guam
June developed from a disturbance over the Caroline Islands and initially moved slowly in weak steering winds. It turned north on 18 November and began intensifying rapidly. Its central pressure fell by about 90 hPa in 24 hours.
On 19 November, a reconnaissance aircraft measured 875 hPa near the edge of June's eye. The archive records that minimum pressure together with peak one-minute winds of 160 kt. June then weakened while moving north through the Philippine Sea.
Island flooding and an offshore turn
June's center stayed west of Guam, but wind and flooding still caused damage on the island. Losses were estimated at US$1.3 million in 1975 values, and at least 29 people were left homeless. Several atolls in Yap also suffered flood damage to property and crops; no deaths were reported.
The storm accelerated into the midlatitude westerlies and became extratropical on 24 November. Its later circulation continued toward the Aleutian Islands and Siberia, ending the long northward passage from tropical waters.

QUICK ANSWERS
June in brief
What was Typhoon June's highest wind speed?
184 mph, the highest one-minute sustained wind in its tropical stage, recorded on Nov 19, 1975, 12:00 PM UTC.
What category was Typhoon June?
Category 5 at its peak on the Saffir–Simpson one-minute wind scale, first reaching Category 5 on Nov 19, 1975, 03:00 AM UTC. Other agencies classify storms differently.
What was Typhoon June's lowest pressure?
875 mb, the minimum central pressure recorded during its tropical stage, on Nov 19, 1975, 12:00 PM UTC.
When did Typhoon June occur?
The archived track runs from Nov 15, 1975, 12:00 AM UTC to Nov 25, 1975, 06:00 PM UTC, with the tropical stage from Nov 15, 1975, 12:00 AM UTC to Nov 23, 1975, 09:00 PM UTC.
Where did Typhoon June form?
In the Western Pacific basin, in the 1975 season. Its first archived position is 8.1°N, 146.4°E on Nov 15, 1975, 12:00 AM UTC.
Did Typhoon June make landfall?
No archived position places Typhoon June's center over land, but positions are six-hourly and a brief landfall can fall between them.
METHODOLOGY
Data sources and limitations
The map and summary are generated from NOAA's IBTrACS v04r01 archive. Wind and category use US-agency records; minimum pressure is calculated during the tropical stage, with the archive's pressure source retained. Category 5 refers to the Saffir–Simpson one-minute wind scale; local agencies may use different classifications. Coastlines use Natural Earth's 1:10m land data.
Track distance adds great-circle distances between consecutive observations, excluding gaps over 12 hours. This track has no gaps over 12 hours. The line shows the storm's center, not its size, rainfall or flood extent. Converted wind speeds are rounded to the nearest whole unit.
